A HD radio tuner is included as standard, and with the ability to play audio visual content from CD DVD and MP3s, you\u2019ll always be able to stay entertained whenever you\u2019re out and about. Could this be the best car stereo for you? Get to the end of this review to find out.\r\n\r\nWhy We Like It - Pioneer AVH-4200NEX\r\nThe Pioneer AVH 4200NEX head unit is a very popular choice for a head unit since it comes with support for both Apple car play and Siri eyes free. The car stereo is SiriusXM ready, and with a 7-inch touch screen, audio visual content from your DVD will look absolutely stunning.\r\n\r\nPerformance\r\nWith an easy to navigate user interface, it won\u2019t be long before you get used to operating this Pioneer DVD receiver since everything feels so intuitive. It\u2019s 7-inch display is also larger than the one on the pioneer avh-1300nex and very responsive to touch. Navigation is quite easy, and if you ever get lost, there\u2019s the home button at the bottom center of the screen that takes you back to where you began. In most car stereos, the sound quality is only as good as the speakers installed, but you will be able to make some adjustments to the sound through the 13-band graphic equalizer.\r\nDesign\r\nThe controls on this Pioneer AVH head unit are all located on the bottom panel of the touch screen display. This is different from the controls on the boss audio bv9358b that are located on the left of the screen. The center home button stands out because it's raised, and the other volume, skip track, mute and mode buttons are covered in a thin membrane. You won\u2019t find any inputs on the front of the touchscreen, but once you tilt it forward, you\u2019ll have access to its SD card slot, DVD-ROM port and the 3.5mm audio input jack. For the USB port, you\u2019ll have to get a USB Aux Flush Mount (sold separately) which will allow a USB and auxiliary port to be installed onto the dash, or you could opt for the 2 that are found in the rear.\r\nValue\r\nIf all you want to do is be able to play music from your phone through your car stereo, the Pioneer AVH 4200NEX is more than able to meet your needs. When driving, you\u2019ll also be able to get navigation through the apps that you\u2019re using. There\u2019s Apple maps from Apple car play, and Google maps from Android Auto, and both of them are great at guiding you to your desired destination. You can still use both apps on the atoto a6, and you\u2019d still get the same screen real estate there that you\u2019d get on this Pioneer 4200NEX.\r\nPioneer AVH-4200NEX Wrap Up\r\nOnce you go for the Pioneer AVH car stereo head unit, you\u2019ll be able to convert your car\u2019s dash into an infotainment center that not many other car stereos can match. Go ahead and check it out on Amazon, and see what other first time users had to say about it.
